Abstract
Abstract A methacrylimide-containing polymer comprising a polymer (A) comprised of 5-100 weight % of units represented by the formula (I): ##STR1## wherein R is H or C1-20 hydrocarbon group, and 0-95 weight % of units derived from an ethylenic monomer, wherein a polymer derived from at least one ethylenic monomer has been grafted onto the polymer (A). The methacrylimide-containing polymer is used as a blend with another thermoplastic polymer.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
102 words
A methacrylimide-containing polymer produced by graft-polymerizing at least one ethylenic monomer onto a polymer (A) comprised of 5 to 100% by weight of methyacrylimide ring-containing structural units represented by the following Formula (I): ##STR4## wherein R represents a hydrogen atom or an aliphatic, aromatic or alicyclic hydrocarbon group having 1 to 20 carbon atoms, and 0 to 95% by weight of structural units derived from an ethylenic monomer, wherein the graft polymerization is carried out after said polymer (A) has been reacted with at least one compound having a functional group to form a thermoplastic polymer (B) having grafting active sites therein.
Claim 2
Dependent Claim
102 words
A methacrylimide-containing polymer produced by graft-polymerizing at least one ethylenic monomer onto a polymer (A) comprised of 5 to 100% by weight of methyacrylimide ring-containing structural units represented by the following Formula (I): ##STR4## wherein R represents a hydrogen atom or an aliphatic, aromatic or alicyclic hydrocarbon group having 1 to 20 carbon atoms, and 0 to 95% by weight of structural units derived from an ethylenic monomer, wherein the graft polymerization is carried out after said polymer (A) has been reacted with at least one compound having a functional group to form a thermoplastic polymer (B) having grafting active sites therein.
Claim 3
Dependent Claim
38 words
A methacrylimide-containing polymer according to claim 1, wherein the grafting active sites comprise a functional group selected from the group consisting of a methallyl group, an allyl group, a methacryloyloxy group, an acryloyloxy group and an epoxy group.
